extends <a href="http://docs.oracle.com/javase/6/docs/api/java/lang/Object.html?is-external=true" title="class or interface in java.lang">Object</a>
implements <a href="../../../../../org/apache/commons/lang3/reflect/Typed.html" title="interface in org.apache.commons.lang3.reflect">Typed</a>&lt;T&gt;</pre>
<div class="block"><p>Type literal comparable to <code>javax.enterprise.util.TypeLiteral</code>,
 made generally available outside the JEE context. Allows the passing around of
 a "token" that represents a type in a typesafe manner, as opposed to
 passing the (non-parameterized) <a href="http://docs.oracle.com/javase/6/docs/api/java/lang/reflect/Type.html?is-external=true" title="class or interface in java.lang.reflect"><code>Type</code></a> object itself. Consider:</p>
 <p>
 You might see such a typesafe API as:
 <pre>
 class Typesafe {
   &lt;T&gt; T obtain(Class&lt;T&gt; type, ...);
 }
 </pre>
 Consumed in the manner of:
 <pre>
 Foo foo = typesafe.obtain(Foo.class, ...);
 </pre>
 Yet, you run into problems when you want to do this with a parameterized type:
 <pre>
 List&lt;String&gt; listOfString = typesafe.obtain(List.class, ...); // could only give us a raw List
 </pre>
 <code>java.lang.reflect.Type</code> might provide some value:
 <pre>
 Type listOfStringType = ...; // firstly, how to obtain this? Doable, but not straightforward.
 List&lt;String&gt; listOfString = (List&lt;String&gt;) typesafe.obtain(listOfStringType, ...); // nongeneric Type would necessitate a cast
 </pre>
 The "type literal" concept was introduced to provide an alternative, i.e.:
 <pre>
 class Typesafe {
   &lt;T&gt; T obtain(TypeLiteral&lt;T&gt; type, ...);
 }
 </pre>
 Consuming code looks like:
 <pre>
 List&lt;String&gt; listOfString = typesafe.obtain(new TypeLiteral&lt;List&lt;String&gt;&gt;() {}, ...);
 </pre>
 <p>
 This has the effect of "jumping up" a level to tie a <code>java.lang.reflect.Type</code>
 to a type variable while simultaneously making it short work to obtain a
 <code>Type</code> instance for any given type, inline.
 </p>
 <p>Additionally <a href="../../../../../org/apache/commons/lang3/reflect/TypeLiteral.html" title="class in org.apache.commons.lang3.reflect"><code>TypeLiteral</code></a> implements the <a href="../../../../../org/apache/commons/lang3/reflect/Typed.html" title="interface in org.apache.commons.lang3.reflect"><code>Typed</code></a> interface which
 is a generalization of this concept, and which may be implemented in custom classes.
 It is suggested that APIs be defined in terms of the interface, in the following manner:
 </p>
 <pre>
   &lt;T&gt; T obtain(Typed&lt;T&gt; typed, ...);
